Documentation.

The field guide walks you through the interface with screenshots and animated examples. Start there if you’re meeting ChooChooTracker for the first time.

The user manual is the reference for instruments, effects, commands and settings. Keep it nearby when you want to go deeper.

Never used a tracker? Get ready for a bit of a learning curve. You may want to watch quickstart guides from other similar trackers (LSDJ, ChipNomad, LittlePiggyTracker, PocketTracker, etc.).
